Abstract: PURPOSE: A 3D tracking system of a surgical instrument, and a position detection method using the same are provided to sense a 3D coordinate and modification of an object. CONSTITUTION: A 3D tracking system(100) comprises a photographing part(110), a recognition part(120), an extracting part(130), and an operation part(140). The photographing part takes a photograph of an object as an image and offers the image to the 3D tracking system. The recognition part recognizes a marker attached to the object by binary-coding the image. The extracting part extracts a 2D coordinate of the marker. The extracting part designates a range determined as a similar region in the binary-coded image to a group. The operation part changes the 2D coordinate into a 3D coordinate by using internal parameter which is determined by a camera of the photographing part.
